A LIEN is a legal right granted to a creditor by a court of law that allows them to secure payment of a debt from a debtor. A payment guarantee is a form of LIEN that guarantees payment of a debt or other financial obligation. It is usually used when a borrower is unable to make payments on their own and requires a third party to guarantee the payment. The LIEN is then placed on the property of the borrower, which serves as collateral for the loan.
